This is a simple problem. You are only using
use for loop to iterate through all items like,
for(int i=0; i<datamodel.size(); i++){
doNormalPostOperation(i)
}
and in doNormalPostOperation method
public void doNormalPostOperation(int i) {
// PREVIOUS CODE
#Override
protected Map<String, String> getParams() {
params.put("id", datamodel.get(i).getINSURANCE_ID() + "");
// REMAINING PARAMS WITH SAME datamodel.get(i) item
}
}
which is causing that issue and only sending first item. You will need to iterate through all items to generate parameters and send to server, or else you can combine them to one json array and modify the code server side.

First you collect the Data from sqltables
/* Collecting Information */
public Cursor getAllData() {
String selectQuery = "Select * from "+TABLE_MEMBER;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
return cursor;
}
public JSONObject createJsonObject(){
Cursor cursor = getAllData();
JSONObject jobj ;
JSONArray arr = new JSONArray();
cursor.moveToFIrst();
while(cursor.moveToNext()) {
jobj = new JSONObject();
jboj.put("Id", cursor.getInt("Id"));
jboj.put("Name", cursor.getString("Name"));
arr.put(jobj);
}
jobj = new JSONObject();
jobj.put("data", arr);
}
public void postJsonToServer(){
JSONObject js = createJsonObject();
String url = "YOUR -- Post Url";
JsonObjectRequest jsonObjReq = new JsonObjectRequest(
Request.Method.POST,url, js,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
msgResponse.setText(response.toString());
hideProgressDialog();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hideProgressDialog();
}
}) {
/**
* Passing some request headers
* */
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
}

You can go through this:
Get all the data which you want to send, via select query and store this data in a array list.
Using GSON library you can convert that arraylist into json data
Now you have to create an API which receive that json data and parse it and insert every record to database.
On the app end you have to hit that API and pass json data to it.

Cannot resolve symbol notifyDatasetChanged

I am working with an application where i get records from my azure database and insert it into an array, and the listview must display my array. My error comes when i try to call the method notifyDatasetChanged, Here is my code:
Button search;
EditText Esearch;
ListView list;
BaseAdapter ADAhere;
Connection connect;
List<Map<String,String>> MyData = new ArrayList();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.srail, container, false);
search = (Button)rootView.findViewById(R.id.btnSearch);
Esearch = (EditText)rootView.findViewById(R.id.srch);
list = (ListView)rootView.findViewById(R.id.view);
search.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
CheckLogin checkLogin = new CheckLogin();
checkLogin.execute("");
String[] fromwhere = { "NAME","PRICE","RANGE","SUPPLIER","SIZE" };
int[] viewswhere = {R.id.Name_txtView , R.id.price_txtView,R.id.Range_txtView,R.id.size_txtView,R.id.supplier_txtView};
ADAhere = new SimpleAdapter(getActivity(), MyData,R.layout.list_products, fromwhere, viewswhere);
list.setAdapter(ADAhere);
}
});
return rootView;
}
public class CheckLogin extends AsyncTask<String, String, String> {
String z = "";
Boolean isSuccess = false;
ProgressDialog progress;
#Override
protected void onPreExecute() {
progress = ProgressDialog.show(getActivity(), "Searching...",
"Listview Loading! Please Wait...", true);
}
#Override
protected void onPostExecute(String r) {
progress.dismiss();
Toast.makeText(getActivity(), r, Toast.LENGTH_SHORT).show();
if (isSuccess) {
Toast.makeText(getActivity(), "Search Successfull", Toast.LENGTH_LONG).show();
//finish();
}
}
#Override
protected String doInBackground(String... strings) {
String Search = search.getText().toString();
try {
ConnectionHelper conStr = new ConnectionHelper();
connect = conStr.connectionclass(); // Connect to database
if (connect == null) {
z = "Check Your Internet Access!";
} else {
// Change below query according to your own database.
String query = "select * from cc_rail where rail_name='" + Search.toString() +"' ";
Statement stmt = connect.createStatement();
ResultSet rs = stmt.executeQuery(query);
while (rs.next()) {
Map<String, String> datanum = new HashMap<String, String>();
datanum.put("NAME", rs.getString("RAIL_NAME"));
datanum.put("PRICE", rs.getString("RAIL_UNIT_PRICE"));
datanum.put("RANGE", rs.getString("RAIL_RANGE"));
datanum.put("SUPPLIER", rs.getString("RAIL_SUPPLIER"));
datanum.put("SIZE", rs.getString("RAIL_SIZE"));
MyData.add(datanum);
}
ADAhere.notifyDatasetChanged();
z = " successful";
isSuccess = true;
connect.close();
}
} catch (Exception ex) {
isSuccess = false;
z = ex.getMessage();
}
return z;
}
}
The Error comes in this portion of the code:
String query = "select * from cc_rail where rail_name='" + Search.toString() +"' ";
Statement stmt = connect.createStatement();
ResultSet rs = stmt.executeQuery(query);
while (rs.next()) {
Map<String, String> datanum = new HashMap<String, String>();
datanum.put("NAME", rs.getString("RAIL_NAME"));
datanum.put("PRICE", rs.getString("RAIL_UNIT_PRICE"));
datanum.put("RANGE", rs.getString("RAIL_RANGE"));
datanum.put("SUPPLIER", rs.getString("RAIL_SUPPLIER"));
datanum.put("SIZE", rs.getString("RAIL_SIZE"));
MyData.add(datanum);
}
ADAhere.notifyDatasetChanged();

write
ADAhere.notifyDataSetChanged();
instead of
ADAhere.notifyDatasetChanged();
You wrote small s instead of S
This is more better practice to write this code in onPostExecute instead of writing this is doInBackground

Your problem is with the way you write the method name notifyDataSetChanged() (you used a small s in set), so it's normal that it does not recognize it
Change this line
ADAhere.notifyDatasetChanged();
with
ADAhere.notifyDataSetChanged();

You have created BaseAdapter and trying to notify the adapter. Create an ADAhere object as a SimpleAdapter which extends BaseAdapter

Transaction ID set correctly, but displayed only a submit later

My code gives correct response and sets transaction ID correctly. But on screen, the ID is missing the first time I submit, and when I go back and submit again, then the ID on screen is the ID of the first transaction.
On the first submit, this is rendered:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID:
On the second submit, this is rendered:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID: NUFEC37WD537K5K2P9WX
I want to see the second screen the first time I submit.
Response to the first submit:
D/TID IS: ====>NUFEC37WD537K5K2P9WX D/UID IS:
====>27W3NDW71XRUR83S7RN3 D/Response-------: ------>{"tid":"NUFEC37WD537K5K2P9WX","uid":"27W3NDW71XRUR83S7RN3","status":"ok"}
Response to the second submit:
D/TID IS: ====>18R6YXM82345655ZL3E2 D/UID IS:
====>27W3NDW71XRUR83S7RN3 D/Response-------: ------>{"tid":"18R6YXM82345655ZL3E2","uid":"27W3NDW71XRUR83S7RN3","status":"ok"}

Because you have used Volley library which is already asynchronous, you don't have to use AsyncTask anymore.
Your code can be updated as the following (not inside AsyncTask, direct inside onCreate for example), pay attention to // update TextViews here...:
...
String url = "http://www.example.com/index.php";
RequestQueue requestQueue = Volley.newRequestQueue(this);
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject json_Response = new JSONObject(response);
String _TID = json_Response.getString("tid");
String _uid = json_Response.getString("uid");
String _status = json_Response.getString("status");
String tid_m =mytid.setTId_name(_TID);
Log.d("TID IS","====>"+tid_m);
Log.d("UID IS","====>"+_uid);
// update TextViews here...
txtTransId.setText(_TID);
txtStatus.setText(_status);
...
} catch (JSONException e) {

requestQueue.add(postRequest);

P/S: since the reponse data is a JSONObject, so I suggest you use JsonObjectRequest instead of StringRequest. You can read more at Google's documentation.
Hope it helps!

Your line of code should be executed after complete execution of network operation and control comes in onPostExecute(); of your AsyncTask.
confirm_tId.setText(_tid);

How do I convert an ordinary listview to a multi-select listview?

I have been having a problem lately, I have successfully created a listview in the FillList method that displays the items that i need. That is all well. The problem is how do I convert it to a multi-select checkbox like style so that when I select an item it will just be stored in an array for later use. Any insight is helpful.
Here is my PathfinderUpdate.java:
public class PathfinderUpdate extends Fragment {
ConnectionClass connectionClass;
EditText edtproname, edtprodesc;

lstpro = (ListView) rootView.findViewById(R.id.lstproducts);
btnrefresh = (Button) rootView.findViewById(R.id.btnrefresh);
pathid = "";
FillList fillList = new FillList();
fillList.execute("");
btnrefresh.setOnClickListener(new View.OnClickListener(){
#Override

Fill.execute("");
}

Check this out i believe its much more close to the new design guidelines!!!

You can create your own adapter and customise list item.
here is a tutorial about list view.
for your questions. chapter 15 might be what you have been looking for.

How to load GridView images with AsyncTask?

I have, below the following fragment that populates a gridview with Bitmaps from URLs. The problem is that I know it's very 'heavy' work and done on the UI Thread so it's slowing the fragment down when loading the grid.
I've read that an AsyncTask is needed to carry out the 'heavy' work in the background but I can't find anything that seems to fit with what I want.
public class HomeFragment extends Fragment {
protected static final String TAG = null;

How to load GridView images with AsyncTask?
Downloading images as Bitmap in HomeFragment. Use NetworkImageView from Volley in layout of GridView item for loading images in GridView.
Instead of storing Bitmap, store image url in ImageItem.
See following tutorial for more help:
Using NetworkImageView

AsynTask class
public class GridDataAsyncTask extends AsyncTask<GridDataAsyncTask.GridCallback, Void, GridAdapter> {
public interface GridCallback {
void onAdapterReady(GridAdapter adapter);
}
private GridCallback mCallBack;
#Override
protected GridAdapter doInBackground(GridCallback... callbacks) {
mCallBack = callbacks[0];
// TODO get data and create grid adapter
return adapter;
}
#Override
protected void onPostExecute(GridAdapter gridAdapter) {
super.onPostExecute(gridAdapter);
mCallBack.onAdapterReady(gridAdapter);
}
}
Activity
public class GridActivity extends AppCompatActivity implements GridDataAsyncTask.GridCallback {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new GridDataAsyncTask().execute(this);
}
#Override
public void onAdapterReady(GridAdapter adapter) {
// TODO set adapte to GridView
}
}

Best you can do is use http://developer.android.com/reference/java/util/concurrent/ThreadPoolExecutor.html and make a lru cache and place the images in lru cache.
Example is given in android tutorials
http://developer.android.com/training/displaying-bitmaps/cache-bitmap.html

As suggested by fractalwrench and Budius, Picasso was a very good and VERY easy solution to this. All I had to do was to pass the photo url instead of the entire BitMap through to my GridView adapter and use Picasso.with(context).load(item.getImage()).into(holder.image); to create the BitMap for the image view. This was so easy to implement and gives me exactly what I need. Thaks
